Not really something that appeals me, Benedict. The woman who wrote this is a little bit to full of herself for my taste. I've felt that spark two times now of 'she might be the one' and I think it's a big assumption of someone to say that this doesn't mean a thing.
Each to their own
Judging by your recent experience though you'd probably be happier in love were you to tame your impulse to psych yourself up with thoughts that the next person you meet is the one. Puts a
lot of pressure onto you and onto any fledgling relationship, and makes any failure far more traumatic.
The initial presence of a spark makes it a lot more appealing to go for a relationship with someone and the long term presence of a spark is needed to struggle through all the tougher times that will happen, but for my money I'd always be very sceptical of the initial spark as it's a notoriously fickle and misguided sensation, almost invariably driven by the projection of your hopes and dreams onto someone in the absence of better data about them, which as you get to know them better can lead to bitter disappointment. Now the long term spark is fantastic, if you can keep that going you're on to something.
Overall, and these are just casual observations based on this thread from a total stranger and as such of little value, but overall it seems that you felt a spark for this person early on and without really having the chance to know them that well, making it a spark based more on a concept of them that you'd projected to fill the blanks than on the actual person. Then when you saw other aspects that contradicted things you'd made up about her you felt like you'd had your heart broken, and from what you say of how she says she's feeling (although you're sceptical of it), it sounds to me like she's been through a similar process.
So in this case a spark did mean something. It meant that you (and her) got really hurt, hopefully not enough to leave either permanently bitter, but clearly very hurt and quite unecessarily so. Some sparks may stand the test of time and mean something more, and to that degree I also disagree with that blog entry, but for your own sake keep something of yourself back that remembers that the initial spark might be misleading, you'll be hurt less for it.
And one thing that blog entry did say well -
But above all, do not go prodding around trying to revive tattered, old feelings, or obsessing about whether or not you actually have "love", it is really unimportant.
Absolutely true. Don't try to maintain feelings based on an initial sense of someone that was wrong, and don't spend so much time worrying about whether this counts as love and she counts as the one, especially not early on. Early on it
always feels really exciting.
